Setting the Time Code
Setting the Time Code and User Bits
This unit can set, display, record and play back the
time code and user bits.
Note
The items explained in this section can be set only
when you record in DVCAM format.
Using the Internal Time Code
Generator
You can set the initial time code value generated by
the internal time code generator. In addition, you can
set the user bits to record data such as the date, time,
scene number, reel number, or other useful
information. The time data settings are set by using the
menu.
For details on the menu, see "Chapter 5 Adjusting and
Setting Through Menus" on page 54 (GB).
To set the initial time code value
This section describes how to set the time code's initial
value.
Notes
• The time code can be set only in a DVCAM format
recording. It cannot be set in a DV format recording.
Make sure to set REC MODE on the VTR SET menu
to DVCAM.

Notes
• When this item is set to EXTERNAL, the time code
input via the DV jack and the user bits set in UB
PRESET are recorded.
• When you set REC MODE on the VTR SET menu to
DV SP, this item cannot be used. Even if this item is
set to EXTERNAL, when you set REC MODE on the
VTR SET menu to DV SP, the setting becomes
invalid and the unit records the internal time code.
• When this item is set to EXTERNAL, the INPUT
SELECT selector on the front panel is set to DV, and
no signal is input via the DV jack, or the software of
the editing controller does not output a time code, if
you start recording, bars (– –:– –:– –:– –) are
recorded as time code. At the point that the input of a
signal begins, the time code of that signal will be
recorded.
• When this item is set to EXTERNAL, if you input
time code to the DV jack that is not continuous or
does not advance correctly, the value of the recorded
or displayed time code may not be equal to the actual
value of the input one. If you use a tape with this
problem, you may not be able to perform search or
edit, depending on the devices you use.
To set the time code when the recording
starts
Set TC MAKE on the TC/UB SET menu to select the
time code to be recorded when recording starts.
REGEN: The time code value is set to continue the
time code from the time code already recorded on
the tape. If you start recording from a blank
portion of the tape, the time code starts from
00:00:00:00.
PRESET: The time code starts from the value set in
TC PRESET on the TC/UB SET menu.

Select RESET in step 4, then press the EXEC button.
To set the advancement mode
Set TC RUN on the TC/UB SET menu to switch the
advancement mode (counting up).
REC RUN: Time code advances only while
recording.
FREE RUN: Time code advances even when the
unit is not recording. This mode is used to set the
current time as the initial time code value.
Notes
• If you set the advancement mode to FREE RUN, the
time code will be updated by the internal clock while
the unit's power is off. The time code may have been
delayed or advanced somewhat if you turn on the unit
power again, play back a tape, or set the INPUT
SELECT selector to DV.
• If the internal backup battery charge is exhausted, the
time code of the FREE RUN setting will be
initialized. The internal backup battery is fully
charged if you connect the power to the unit for about
8 hours. A fully charged internal battery can run for
about two weeks.
To set the frame mode (For NTSC only)
Set TC FORMAT on the TC/UB SET menu to switch
the frame mode.
AUTO: Automatically sets the mode in accordance
with the loaded tape.
If nothing is recorded on the tape, the mode is set
to the non-drop frame mode. If the unit cannot
read the frame mode correctly from the tape, the
unit will use the mode that was set in the last
position it was able to read correctly on the tape. If
you remove the cassette, the mode of the last
position it was able to read correctly is cleared and
the mode is set to the non-drop frame mode. If TC
MAKE is set to PRESET, the mode is also set to
the non-drop frame mode.
DF: Selects the drop frame mode.
NDF: Selects the non-drop frame mode.
1-10
To set the value of the user bits
You can set the user bits as eight-digit hexadecimal
values (base 16) to have the date, time, scene number,
and other information inserted into the time code track.
Note
The user bits can be set only in a DVCAM format
recording. They cannot be set in a DV format
recording.

Chapter 3 Setting the Time Code (GB)
Notes
• In a DV format recording, the drop-frame mode is
used automatically.
• When the NTSC/PAL select switch on the rear panel
is set to PAL, the unit works as a PAL model.
Therefore, the time code generated by the unit during
recording in the DVCAM format is that of the non-
drop frame mode. Even if an NTSC formatted signal
is input to the DV jack, the time code generated by
the unit is non-drop frame mode as long as the
NTSC/PAL select switch is set to PAL, regardless of
the setting of this item. If you intend to set the unit to
generate the time code in the drop frame mode, set
the NTSC/PAL select switch to NTSC.
